Field notes from maintenance practice

Temperature is the clock for the roller train: density must be achieved before the mat cools below the cessation temperature (often ~85–90 °C), which on a cold, windy day can be only minutes. Log mat temperature behind the screed and you can predict how many roller passes you have — the difference between a passing core and a costly re-lay. Asphalt compaction has a closing window: roll too hot and the mat shoves, too cold and the aggregate won't move and density falls short — so the temperature behind the screed and the time-to-cold dictate the rolling pattern.

Consistency makes the numbers meaningful: measure at the same point, with the same instrument, at sensible intervals (continuous where the risk is high, spot-checks where it is low). The in-range percentage is the metric to watch — a band that quietly drifts from 100% toward 95% is telling you something is changing before any single reading alarms.

About Asphalt Laydown Temperature Dashboard

This dashboard turns scattered mat temperature checks for hot-mix asphalt during paving into a monitored series: log a reading whenever you measure and it tracks the latest value, the average, the min/max range, the percentage of readings inside the acceptable band and the number of excursions — the everyday telemetry picture, computed in your browser with no logger subscription. The default acceptable band is 135–160 °C at laydown for typical dense-graded hot mix (mix-specific; check the JMF).

How to use Asphalt Laydown Temperature Dashboard

  1. 1Log a reading whenever you measure — each is timestamped and stored in your browser.
  2. 2The dashboard shows latest, average, min/max, in-range % and an excursion count against the acceptable band.
  3. 3Watch the sparkline and the in-range percentage — a falling in-range % is your early warning before a hard excursion.

Frequently asked questions

What is the acceptable mat temperature range for hot-mix asphalt during paving?+

The default band is 135–160 °C at laydown for typical dense-graded hot mix (mix-specific; check the JMF). Treat it as a sensible starting point — your own specification, regulator, equipment manual or product datasheet sets the authoritative limits, and you can read your true band straight off the worst case those documents allow. Edit the readings against whatever band applies to you.

Why does cold-weather paving fail to reach density?+

The mat cools too fast to compact: thin lifts on a cold base in wind can drop below the compaction cessation temperature in minutes, freezing the aggregate skeleton before the rollers achieve density. Voids stay high, and the pavement ravels and lets water in. Mitigations are warmer mix, thicker lifts (they hold heat longer), rollers right behind the paver, and material-transfer vehicles. Monitoring mat temperature tells the roller operator exactly how much time the day's conditions allow.

How often should I log mat temperature readings?+

Match the interval to the consequence and the rate of change: where an excursion spoils product or risks safety, log continuously (or as often as you can sample); where it is merely informative, daily or per-shift spot checks suffice. The in-range % and excursion count only mean something if your sampling is regular — sparse, irregular readings hide the excursions between them.

Is my logged data private?+

Yes — every reading is stored in this browser's localStorage on your device and nothing is uploaded to any server, which also makes the dashboard usable on sites with strict data policies. For shared, audit-grade records across a team or for regulatory retention, export the values into your own system.
